The build playbooks have no effect on the libvirt repo itself. Those playbooks
are only good for building the respective projects in your local VM. In order
to disable ubuntu-1804 in our upstream CI we need to drop the OS target from
libvirt's ci/manifest.yml (in libvirt repository) file and then regenerate
gitlab-ci.yml with lcitool using the manifest.
